LEO allows also calibration of the CO2 and O2 sensors by using an external gas meter (not hereby

To run the CO2/O2 User Calibration, it is necessary to follow the instructions below:
1. Connect the external gas meter to the incubator in order to read the CO2 and O2 compositions inside
the incubator (see Figure 103).
Figure 103. External gas meter connection to the incubator.
Once you have connected the external gas meter to the incubator, wait until it steadily reads CO2 and
O2 values and make sure that the system remains stable over time and the incubator is closed. When
